Outside of canon, but within physics, a baryon sweep would probably erase or at least severely damage Data's positronic brain.
[In response to comment]:
Positrons are positively charged particles with the mass of an electron, presumably confined with circuits that form the basis of artificial neuronic pathways. The potentials required to confine those particles are based on said mass.
Stable baryons (those that would be used in a 'sweep') are also positively charged but with masses at least 2000 times heavier than positrons. They are also readily interpolated into the circuitry because their positive charge would dislodged positrons at any level of kinetic energy (the basis of the Bohr approximation in Quantum Mechanics-- with mass gain of 2000 times, the baryons would have at least that many times kinetic energy as the positrons).
These heavier particles would not respond to the relatively weak potentials need to confine the positrons, and the data bits would simply 'float away', probably fairly quickly.
But alas, I'm down voted because there should be no science in our science fiction.
